data(metrics)A data frame with 3 rows and 5 variables
test: id of the test (in this case a SPARQL query) executed. Example: 'Q9.sparql'.
approach: name of the approach (or engine) used to execute the query.
tfft: time (in seconds) required by approach to produce the first tuple when executing query.
totaltime: elapsed time (in seconds) since approach started the execution of query until the answer i is produced.
comp: number of answers produced by approach when executing query.
